Hi,


I am working on a LES and have some struggle with time averaged data. I activated data sampling for time statistics in fluent and got in post processing mean and rms velocities and rms reynolds stresses. But I also need mean turbulent viscosity to investigate which turbulences are solved and which modeled.

Do I have to write an user defined function to get this or is there an easier way to get more mean values? I would like to avoid UDFs because I did not work with it yet..
I hope you can help me!



Greetings banane5

In 'run calculation' click 'sampling options'. There you can add other variables to average. They have to be defined as 'custom field functions' first but this is easier than writing a UDF.
